USA TODAY - Details have been leaking out here and there of Michelle Obama's wild 50th birthday party over the weekend.
But the best proof of the bash comes from Beyonce, who posted a photo of herself petting Bo.
No, wait, that's Sunny! Bo has white markings.
The star -- Beyonce, not the dog -- wore a sparking gold minidress for the dance party where she performed Single Ladies and Irreplaceable.
People mag reports that first daughters Sasha and Malia "watched in awe."
The magazine also reports that Smokey Robinson greeted Hillary Clinton with a bear hug at the North Portico door, while Bill Clinton chatted with Jennifer Hudson. Top White House adviser Valerie Jarrett was on the arm of NFL veteran and sportscaster Ahmad Rashad.
Also mixing and mingling: James Taylor, Nancy Pelosi, Paul McCartney and John Legend, who sang two different versions of Happy Birthday.
